Type of Battery for STM32U585 MCU

Hi All,We are planning to use STM32U585 series MCU. while going through the datasheet it is mentioned as Vbat with internal charging circuit. Whether we use non rechargeable battery or Supercapacitor for Vbat pin? or it can be used only rechargeable...

Is there a way to output Vref+/2 in an STM32L4R5ZI?

Hi!I'm using the STM32L4R5ZI's DAC to generate a signal, after that I'm using a differential amplifier to eliminate the DC level of the signal (since DAC can only output from 0 to Vref+). For that ampifier I need the value in witch the signal is cent...

I am currently designing a custom PCB and would like to have an integrated ST Link just as in the discovery modules, where could I find the ST Link firmware for this? Thanks a lot in advance.

STM32H743 DMA not working

In the program that transmits the value received from uart4 to uart5, I want to move the value received from uart5 to another buffer, but I move it to HardFault_Handler.what is the reason?And please check if the method of receiving data using the dma...

Problem Implementing QUADSPI

I have few confusions:How do you activate QUADSPI Indirect mode ? Does MX_QUADSPI_Init() activates the Indirect mode ? Is the default mode Indirect mode after initialising QUADSPI ? Do you need to activate it somehow from the software or some command...

STM32 neural network in_data had concated my raw data, but out_data always show 0...

I had check program for erros or not and try to adjust possible parameters ,it's still unworked for out_data @@. Are some ideas, guys?​

I am using STM32L471 controller, I just want to ask that what is the maximum value of decoupling capacitor which can be used at JTAG SWDIO pin of controller, so that there would not be any issue during programing of controller using SWD 4MHz setting.

Ping pong buffers in speech IO

Hi,I am trying to implement a speech IO system using stm32f4 discovery board. For this I am using interrupt for extracting(from digital mic) pcm samples to a buffer & for output(using polling) I am continously writing circularly the same buffer con...

maximum sample time of DAC and signal frequency generated

MCU of STM32L476 series,please let me know the maximum sample time of DAC and the maximum sine signal frequency which can be generated.
